As nitrogen6x boards support different i.MX6 flavors (quad, dual-lite and solo)
the correct CPU revision needs to passed to the kernel, so call get_cpu_rev()
instead of hardcoding it.
Freescale 3.0.35 kernel assumes that the CPU revision is passed passed from the
bootloader.

This is the **board** revision, right?
At first glance, the kernel seems to be getting the silicon revision
from the same place as get_cpu_rev():

Is there a reference to the ATAG that I'm not seeing somewhere?
Please advise,
